Understanding The Determinants Of The Cost Of Coronary Artery Bypass Graft Surgery, Hun Lee

Electronic Thesis and Dissertation Repository

Introduction: The relationship between patient demographics, clinical factors, and cost of coronary artery bypass graft (CABG) is complex. Investigation of these relationships is important to aid clinical practice and inform reimbursement models. This thesis analyzes multiple different domains in order to understand the significant factors that impact the cost of CABG at the London Health Sciences Centre (LHSC).

Methods: Model selection, construction of nested descriptive models, exploration of mediation analysis of the impact of peri-operative factors and cost through length of stay, and construction of estimative models were performed.

Results: Several baseline characteristics, socio-demographics, peri-operative variables, and post-operative variables were …

Renewable-Energy Resources, Economic Growth And Their Causal Link, Yiyang Chen

Electronic Thesis and Dissertation Repository

This thesis examines the presence and strength of predictive causal relationship between re-newable energy prices and economic growth. We look for evidence by investigating the cases of Norway, New Zealand, and Canada’s two provinces of Alberta and Ontario. The usual vectorautoregressive model (VAR) and its various improved versions still assume constant parametersover time. We devise a Markov-switching VAR (MS-VAR) model in order to accommodate the observed time-dependent causal relation changes. Our proposed modelling approach is induced by the hidden Markov model methodologies in terms of an online parameter estimationthrough recursive filtering. The parameters of the MS-VAR model are governed by …

Essays On Criminal Behaviour, Human Capital Formation, And Mental Health, Diego F. Salazar

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters that contribute to the study of some of the negative consequences of incarceration and their relation with the life-cycle choices of juvenile offenders.

Chapter 2 studies the causal relationship between incarceration and mental health problems. In this chapter, I use different matching estimators to identify the causal effects of incarceration over several dimensions of mental health using data from a survey of juvenile offenders, the Pathways to Desistance (PTD) survey. My findings show that being incarcerated for the first time, between 17 and 18 years old, increases depression by at least 0.18 standard deviations …
